TECHNICAL FIELD

The present invention relates to a form board that is a nonmetallic form board (sheathing board) with heat insulation properties (e.g., made of a foam material such as Styrofoam or a plastic material) used as an internal/external insulator for construction, without the removal of the form board after pouring concrete, the form board being adapted such that a plurality of form boards is interconnected, and a method of constructing a form using the form board. More particularly, the present invention relates to a form board that is provided with a recessed groove portion having a tie through-hole such that an H-bar is mounted to the recessed groove portion, in the state in which a flat tie is arranged through each of both edges of a plurality of form boards for vertical walls, which are spaced apart from each other at regular intervals in a width direction and simultaneously continue to be vertically arranged in a longitudinal direction for pouring concrete, and a method of constructing a form using the form board.

BACKGROUND ART

When buildings are generally constructed, a plurality of form boards forming the frame of a wall is used to form the wall, which defines the external appearance of the buildings, transverse bars (pipes) are embedded in concrete poured between the form boards to function as respective frame members and are simultaneously connected to hooks by wedges to be installed to end portions protruding outward from the form boards in order to endure the pressure of concrete between the form boards, or building materials, such as a flat tie for mounting a reinforcement plate capable of covering and reinforcing the contact connection portion between the form boards, are used.

By way of example, the process of forming a conventional building wall will be schematically described. After a plurality of form boards are spaced apart from each other at regular intervals in the width direction and are continuously and vertically arranged in the longitudinal direction, concrete is poured into the space between the form boards and is then cured, thereby enabling a predetermined vertical wall to be completed.

In addition, the process of forming a lamination plate (slab) on the upper end portion of the vertical wall is performed by horizontally arranging lumber on the upper end portion of the vertical wall, again arranging plywood on the lumber, fixing the same with nails, pouring concrete in the state in which insulation (dustproof) Styrofoam is placed on the plywood, and then separating and removing the lumber and the plywood.

Meanwhile, when the form boards are continuously arranged in the longitudinal direction, the length of the wall may extend in the longitudinal direction, e.g. by interconnecting the side end portions of the form boards using wires or the like.

However, since the process of separating and removing the form boards after curing concrete is used in the conventional form boards, the separation and removal operation of the form boards is cumbersome. In addition, since the process of installing new insulators to the concrete wall after the removal of the form boards is added, there is a problem in that operation efficiency is generally deteriorated.

Moreover, since a flat tie penetration arrangement structure and an H-bar connection structure are not separately provided in the conventional form boards, there is a problem in that it is inconvenient to connect the components such as the flat tie and the H-bar.

DISCLOSURE Technical Problem

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a form board that is a nonmetallic form board (sheathing board) with heat insulation properties (e.g., made of a foam material such as Styrofoam or a plastic material) used as an internal/external insulator for construction, without the removal of the form board after pouring concrete, capable of providing convenience and practicality since the form board itself performs an insulation function and there is no need for the separate removal operation of the form board after curing the concrete and thus the installation operation of insulators, and a method of constructing a form using the form board.

In addition, it is another object of the present invention to provide a form board that is provided with a recessed groove portion having a tie through-hole such that an H-bar is mounted to the recessed groove portion, in the state in which a flat tie is arranged through each of both sides of a plurality of form boards for vertical walls, which are spaced apart from each other at regular intervals in the width direction and simultaneously continue to be vertically arranged in the longitudinal direction for pouring concrete, thereby enabling the number of processes and the operating time to be significantly reduced since the connection operation between the form boards is rapidly and easily performed and thus enabling operation efficiency to be improved, and a method of constructing a form using the form board.

In accordance with another aspect of the present invention, there is provided a method of constructing a form using a form board, including preparing a plurality of form boards having tie through-holes in edge portions thereof in order to install a construction form, vertically arranging the form boards which are spaced apart from each other at regular intervals in a width direction and are continuously arranged in a longitudinal direction for pouring concrete, arranging flat ties through the tie through-holes in opposite edges of the form boards which are continuously arranged in the longitudinal direction, and then interconnecting the form boards using H-bars, connecting hooks by wedges through wedge holes in the flat ties protruding outward from the form boards, installing transverse support bars to the hooks, and arranging vertical support bars between the transverse support bars and outer surfaces of the form boards.

Advantageous Effects

BEST MODE

Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below.

As illustrated in FIGS. 1 to 5, a form board, which is designated by reference numeral 10, according to an embodiment of the present invention is adapted to form a desired shape of construction form in such a manner that a plurality of form boards are spaced apart from each other at regular intervals in a width direction so as to define space portions therebetween and are continuously and vertically arranged in a longitudinal direction for pouring concrete.

The form board 10 has a rectangular board shape, and is made of foam so as to be usable as an insulator for pouring the concrete. Tie through-holes 11 are provided at both edge portions of the form board 10 such that each flat tie 20 is arranged through the associated tie through-hole 11.

The flat tie 20 has a tie body 21 and a plurality of gap holding protrusions 22 which protrudes from one surface of the tie body 21 of the flat tie 20 in the direction perpendicular to the surface. The tie through-hole 11 in the form board 10 has a body penetration portion 11 a and a protrusion penetration portion 11 b communicating with each other such that all of the tie body 21 and the gap holding protrusions 22 may pass therethrough. Accordingly, the tie through-hole 11 has a turned T shape, i.e. a structure turned at a right angle and lying on its side.

Each edge connection portion 31 of an H-bar 30 encloses an edge cross-section of the form board 10 and front and rear surfaces adjacent thereto in a “

” form such that the H-bar 30 is fitted to the form board 10. Each edge portion of the form board 10 is provided with a recessed groove portion 12 which is recessed such that the edge connection portion 31 is flush with the associated edge cross-section and front and rear surfaces of the form board 10.

Here, the coupling structure between the flat tie 20 and the H-bar 30 through the recessed groove portion 12 is as follows: the gap holding protrusions 22 of the flat tie 20, arranged through the tie through-hole 11, are respectively spaced apart from the front and rear surfaces of the recessed groove portion 12 at regular intervals; and in this case, the edge connection portion 31 of the H-bar 30 mounted to the recessed groove portion 12 is inserted into the clearance between the surface of the recessed groove portion 12 and the gap holding protrusions 22, and thus the gap holding protrusions 22 are located on and caught by the outer surface of the edge connection portion 31 of the H-bar 30, so as to fix the flat tie 20.

In addition, the recessed groove portion 12 is provided in a plural number throughout the edge of the form board 10. For example, three recessed groove portions are centered on the central portion at both edge portions of the form board 10 at equal intervals, and two recessed groove portions are provided at each of the upper and lower edge portions of the form board 10.

Each edge portion of the form board 10 has a pin through-hole 13 through which pass the associated H-bar 30, for connecting the edges of one form board and another form board, which are continuously arranged in the longitudinal direction, and an associated fixing pin 55 for interconnecting and fixing the edges of the form boards.

Here, the fixing pin 55 has an elongated bar shape, and serves to interconnect the edges of the form boards in the fixed state by passing through the pin through-hole 13. The fixing pin 55 may be made of a PVC material.

In addition, the form board 10 has an adhesive recessed portion 14 which is recessed at the central portion of one surface thereof facing concrete, in order to improve adhesion with the poured concrete.

The central portion of the form board 10 is provided with a plurality of central through-holes 15 for the passage of flat ties 25.

Each flat tie 25 arranged through the associated central through-hole 15 may be fixed by catching a gas holding protrusion 26 of the flat tie 25 by the inner surfaces of the respective central through-holes 15 of a pair of form boards 10 facing each other.

Meanwhile, as illustrated in FIGS. 3 and 5, each separate hook 50 is connected by an associated wedge 51 through wedge holes 21 a and 25 a in both ends of the flat ties 20 and 25, which are exposed to the outside of the form board 10, and thus a transverse support bar 52 may be installed to the hook 50.

Here, a separate vertical support bar 53 for reinforcing the transverse support bar 52 may be arranged in the space between the transverse support bar 52 and the form board 10.

Reference numeral 40 refers to a corner bar for connecting the corner portions of one form board and another form board.

Hereinafter, a method of constructing a form using a form board according to an embodiment of the present invention will be described with reference to the above-mentioned structure. First, a plurality of form boards 10 having tie through-holes 11 in the edge portions thereof is prepared to install a construction form.

Next, the form boards 10 are vertically arranged so as to be spaced apart from each other at regular intervals in the width direction and to continue in the longitudinal direction, for pouring concrete.

Next, flat ties 20 are arranged through the tie through-holes 11 in the opposite edges of each of the form boards 10 which continue in the longitudinal direction, and then the form boards 10 are interconnected using H-bars 30.

Next, hooks 50 are connected by wedges 51 through wedge holes 21 a in the flat ties 20 protruding outward from the form boards 10, transverse support bars 52 are installed to the hooks 50, and vertical support bars 53 are arranged between the transverse support bars 52 and the outer surfaces of the form boards 10. Through such processes, the construction of the form using the form boards according to the present invention is completed.

In addition, an additional flat tie 25 may be mounted through a central through-hole 15 in each form board 10.

Here, the coupling relationship between each of the flat ties 20 and each of the H-bars 30 through a recessed groove portion 12 is as follows: after the flat tie 20 is arranged through each of the tie through-holes 11 such that gap holding protrusions 22 of the flat tie 20 are respectively spaced apart from the front and rear surfaces of the recessed groove portion 12 at regular intervals, each edge connection portion 31 of the H-bar 30 is inserted into the clearance between the surface of the recessed groove portion 12 and the gap holding protrusions 22, and thus the gap holding protrusions 22 are located on and caught by the outer surface of the edge connection portion 31 of the H-bar 30, so as to fix the flat tie 20.

When the form board 10 has the central through-hole 15, the flat tie 25 is provided to have a gap holding protrusion 26 having an inner surface catching structure. The flat tie 25 is arranged in the space between a pair of spaced form boards 10, and the gap holding protrusion 26 of the inner surface catching structure is caught by the inner edge portions of the central through-hole 15 in respective form boards 10 facing each other. Thus, the distance that is set in the width direction in the central portion of each form board 10 may be maintained.

The form boards 10 extend at right angles by connecting the corner portions of the form boards 10 using corner bars 40. Alternatively, when slabs are manufactured, form boards for slabs (not shown), which are horizontally arranged on the upper end portions of the form boards for vertical walls 10 for pouring concrete, are connected to the facing edge portions of the form boards for slabs and form boards for vertical walls using the corner bars 40. Consequently, the form boards for slabs may extend at right angles.

In this state, when concrete is poured into the space between the form boards 10 and cured, a predetermined vertical wall for building is completed.

As described above, in accordance with the form board and the method of constructing a form using the same, the form board is a nonmetallic form board (sheathing board) with heat insulation properties (e.g., made of a foam material such as Styrofoam or a plastic material) used as an internal/external insulator for construction, without the removal of the form board after pouring concrete, and the form board can provide convenience and practicality since the form board itself performs the insulation function and there is no need for the separate removal operation of the form board after curing the concrete and thus the installation operation of the insulators. In addition, since the form board is provided with the recessed groove portion having the tie through-hole such that the H-bar is mounted to the recessed groove portion, in the state in which the flat tie is arranged through each edge of a plurality of form boards for vertical walls, which are spaced apart from each other at regular intervals in the width direction and simultaneously continue to be vertically arranged in the longitudinal direction for pouring concrete, the number of processes and the operating time can be significantly reduced since the connection operation between the form boards is rapidly and easily performed and thus the operation efficiency can be improved.
